Suppose
is a random variable with a distribution that may be
known or unknown (it
can be any distribution) and suppose:
the mean of
the standard deviation of
If you draw random samples of size
, then as
increases, the random variable
which consists of sums tends to be
normally distributed and
~
The Central Limit Theorem for Sums says that if you keep drawing larger and larger samples
and taking their sums, the sums form their own normal distribution (the sampling distribution) which approaches a normal distribution as the sample size increases.
The normal distribution has a
mean equal to the original mean multiplied by the sample size and a standard deviationequal to the original standard deviation multiplied by the square root of the sample size.
The random variable
has the following z-score associated with it:
is one sum.
the mean of
standard deviation of
An unknown distribution has a mean of 90 and a standard deviation of 15. A
sample of size 80 is drawn randomly from the population.
Find the probability that the sum of the 80 values (or the total of the 80 values) is more
than 7500.
Find the sum that is 1.5 standard deviations above the mean of the sums.
Let
= one value from the original unknown population.
The probability question asks you to find a probability for
the sum (or total of) 80 values.
= the sum or total of 80 values. Since

Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue..
sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child

child interact with other kids under doc supervision.
play therapy.
speech therapy.
Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game.
string and beads game.
the more you interact with the child the more effective
Jharna
results you'll get..
please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
but trust the process and be strong and patient as a parent.
